Abstract

A damper, in particular for washing machines having a spin cycle, includes a housing having a central longitudinal axis and at least partially enclosing a housing inner space by housing walls, a tappet which can be displaced in the housing along the central longitudinal axis and is guided out of the housing, fastening members which are arranged at free ends of the housing and of the tappet, and at least one compensation member for compensating a play between the housing walls and the tappet.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A damper, comprising
 a. a housing having a central longitudinal axis and at least partially enclosing a housing inner space by housing walls,   b. a tappet which can be displaced in the housing along the central longitudinal axis and is guided out of the housing, wherein the tappet has at least one friction lining recess,   c. at least one friction lining being arranged in the at least one friction lining recess and rests in a frictional manner against at least one housing wall and/or against a friction insert,   d. fastening members which are fastened to free ends of the housing and the tappet, and   e. at least one compensation member for compensating a play between the housing walls and the tappet.   
     
     
         2 . A damper, comprising
 a. a housing having a central longitudinal axis and at least partially enclosing a housing inner space by housing walls,   b. a tappet which can be displaced in the housing along the central longitudinal axis and is guided out of the housing,   c. fastening members which are fastened to free ends of the housing and the tappet,   d. at least one compensation member for compensating a play between the housing walls and the tappet,
 wherein the at least one compensation member is integrally formed on the tappet, which is manufactured in one piece from plastic material. 
   
     
     
         3 . The damper according to  claim 1 , wherein the at least one compensation member is arranged on the housing. 
     
     
         4 . The damper according to  claim 3 , wherein the at least one compensation member is fastened to the housing. 
     
     
         5 . The damper according to  claim 3 , wherein the at least one compensation member is integrally formed on the housing. 
     
     
         6 . The damper according to  claim 1 , wherein the at least one compensation member has a compensation member length which extends along the central longitudinal axis. 
     
     
         7 . The damper according to  claim 1 , comprising two compensation members. 
     
     
         8 . The damper according to  claim 7 , wherein the two compensation members are oriented in opposite directions with respect to a center plane of the tappet. 
     
     
         9 . The damper according to  claim 1 , wherein the at least one compensation member holds the tappet in the housing. 
     
     
         10 . A damper, comprising
 a. a housing having a central longitudinal axis and at least partially enclosing a housing inner space by housing walls,   b. a tappet which can be displaced in the housing along the central longitudinal axis and is guided out of the housing,   c. fastening members which are fastened to free ends of the housing and the tappet,   d. at least one compensation member for compensating a play between the housing walls and the tappet,
 wherein the at least one compensation member is configured as a lamella, wherein the lamella at least one of extends at least in portions transversely to the central longitudinal axis and is oriented obliquely, wherein the lamella comprises a sinusoidal configuration. 
   
     
     
         11 . The damper according to  claim 1 , wherein at least one of the housing and the tappet is double-T-shaped in cross-section. 
     
     
         12 . The damper according to  claim 11 , wherein at least one of the housing and the tappet is perpendicular to the central longitudinal axis. 
     
     
         13 . The damper according to  claim 1 , wherein the tappet has an intermediate web defining a center plane. 
     
     
         14 . The damper according to  claim 13 , wherein the center plane comprises the central longitudinal axis. 
     
     
         15 . The damper according to  claim 1 , wherein the at least one friction lining recess completely penetrates the tappet. 
     
     
         16 . The damper according to  claim 1 , wherein the at least one friction lining recess has one of a rectangular and diamond-shaped form. 
     
     
         17 . The damper according to  claim 1 , wherein the friction lining recess is bounded by end sides located at the axial ends and longitudinal sides connecting the latter. 
     
     
         18 . The damper according to  claim 17 , wherein at least one end side is configured to be serrated. 
     
     
         19 . The damper according to  claim 1 , wherein the shape of the friction lining is adapted to the shape of a friction lining recess. 
     
     
         20 . The damper according to  claim 1 , wherein the friction lining is configured to be serrated on at least one end side. 
     
     
         21 . The damper according to  claim 1 , wherein the housing has a housing body. 
     
     
         22 . The damper according to  claim 21 , wherein the housing body is made in one piece. 
     
     
         23 . The damper according to  claim 1 , wherein at least one friction insert is arranged on the inside of the housing.
